HOT-WATER H E'ATER.

SPECIFICATION forming part of Letters Patent No. 532,836, dated January22, 1895. i

Application filed September 28, 1894. Serial No. 524,379- (No model.) i

To @ZZ whom it, may concern:

Be it known that LAHORACE K. TALLMAGE,

a citizen of the United States, residing in Buffalo, in the county ofErie and State of New York, have invented certain new and usefulImprovements in Hot-Tater Heaters, of which the following is aspecification.

My invention relates to a new and improved hot water heatin g apparatusby which a large amount of heating surface is obtained at a minimum costVof construction, all of which will be fully and clearly hereinafterdescribed and claimed, reference being had to the accompanying drawings,in which- Figure 1, represents a front elevation of my improved steamboiler complete. Fig.` 2, represents a Vertical section through one sideof the boiler, on or about line a a, Fig. 1. Fig. 3, is a detached sideelevation of onefsection or side of the body of the boiler, showing oneVside of its series of water tubes in their proper position projectingout therefrom. Fig. 4, represents a vertical section through a portionof one of' the sides cutting through the ribbed portion in which thefire box is located. Fig. 5, is a horizontal section on or about line aa, Fig. 2, showing a top View of the removable perforated air tubingsurrounding the inner side of the fire box. Fig. 6, is also a horizontalsection on or about line c c, Fig. 2, illustrating the preferred systemof water tubes. Fig. 7, represents ahorizontal under side view of one ofthe horizontal air tubes that are located in the upper portion of thecombustion chamber as will appearfarther on.

The body of the boiler, containing the water tubes and fire box consistsof the parts l and 1, 2 and,2.A These fourk parts are all provided witha water chamber 3, and two of said parts are provided with alongitudinal tongue 4, projecting out from each narrow side, also with atongue 5, at the bottom and a tongue groove 6, at the top. See Fig. 3.The other two parts, 2 and 2a', are each provided on one of their broadfaces near each side or corner with a longitudinal groove 7, one on eachside, adapted to receive the tongues 4 see Fig. 5, where these parts areshown put together thereby forming a substantially square fire box. Inone of the side parts is an opening communicating with the waterchamber, adapted to receive the inlet pipe 8, and

`through another is an opening leading into the combustion chamber andprovided with the usual door- 9. See Fig. 1. On the lower portion ofeach inner side is a ribbed portion 10, consisting of aseries ofparallel ribs and cross ribs leaving the air spaces 11, between them.bee Fig. 4. -Ihaveshown thesespaces as square, but they may be made inany suitable shape, the object being to interpose a non-conducting bodyof air 'between the fire and water space and thereby keep the coalfromlying close to the side where it is liable to be cooled or deadenedby being too close tothe water in the water space. The object of theseribs is therefore to provide a series of dead air spaces in which theair cannot circulate but is held in said recesses or depressions betweenthe fuel and the Waterside and thereby avoid the objectionabovementioned.

Projecting from the upper inner side of each part l-1-2-2, is a Vseriesof water tubes l2, rigidly secured thereto and communicating with thewater chamber. The outer or free ends 13, of all these pipes l2, areclosed watertight. Two opposite sides l and 1', for instance, are puttogether so that the pipes 12, pass between each other, see Fig. 2, alsoFig. 3, where the alternate pipes are shown by dotted lines, the pipesin one section being placed sufficiently .below the pipes in the otherso as to be substantially central between and below them as shown, onepipe being below the other in a vertical line. The pipes 12a, on theopposite Isections pass at right angles or crosswise between the pipes12, in substantially the same manner, only the pipes of one section passbetween the pipes in the other section in a horizontal plane instead ofvertical as withformerpair of sections, see Fig. 6,"in this connection,where the preferred construction, or arrangement of pipes is shown, inwhich the pipes 12, in the two opposite sections 2 `and. 2a, pass inbetween each other in a horizontal plane, and the pipes 12, in the twoopposite sections l and 1a (which pass at right angles or cross thepipes 12), also 'pass from each section in between each other in ahorizontal plane. rlhis is the preferred construction because more pipescan begot in a given space than in the construction shown in Figs. 2 or3.

IOO

Below the four main sections is the ash box 15, made in the usual wayand provided with a door 1G. two ribs which hold it above the iioor. topis a hollow section 17, having a water chamber 17, and a verticalcentral opening 18. See Fig. 2. It is provided with a downwardlyextending tongue 19, which extends entirely around it and tits in thegroove 6,when put in place. On the top of this section 17, is anothersection 20, having a surrounding water chamber 20% This section isprovided withachamber 21, a smoke pipe hole 22, and with a tongue 23,extending around near the bottom edge and is adapted to lit in thegroove 24, in the top of the section 17. Y This top section beingsquare, can be turned so as to bring the smoke pipe hole 22, either tothe front or back or to any side.

The top portions, and the top of the four main sections, are all heldtogether and provided with a water communication between all of thewater chambers by means of connecting water tubes, 24e. See Figs. 1 and2. The horizontal pipes 25, are each provided with a short branch pipe26, connecting with the narrow sides of the sections i and la, and witha short pipe 26a connecting with the sections 2 and 2. The verticalpipes connected with the pipes 25, extend upward and connect by pipes27, with the upper section and by pipe 28, with the top section 20. i

It will be seen that the above pipes not only provide a watercommunication between the several water chambers but also hold theseveral parts together. b

A series of screw threaded holes, are cut in the reversible top portion,each hole being lled with a plug 34, which is removed when it becomesnecessary to reverse the upper portion having the hole for the smokepipe. These plugs are used to stop the holes left by the connectingpipes when they are re-I moved from said top portion.

Four air pipes 29, extend up to the top of They are located in or about`the fire box. each corner of the `fire box, (see Fig. 2,) and extenddown through the bottom of the ash box, and are open so that the airpasses in,` in the direction of the arrows V, shown in` said Fig. 2. Thetop ends of these pipes 29,

to iit over the top of the pipes 29, so that the horizontal pipes 30,can be set thereon, and

thus be easily removable so that when worn or burned out they can beinstantly replaced by new pipes. `They are put in `place sub-lstantially as shown in Fig. 5. Their free ends At the bottom of the ashbox aref At the are chamfered oit so that they lit together as shownandthe inner sides 32, are` provided with a series of perforations 33. SeeFig. 2. The object of this construction is to carry highly heated air tothe point where it is most required 'to mingle with the gases ofcombustion, andthe object in using metal for this is that it becomesmore highly heated than brick.` Furthermore the tubes being smallconfine the air more closely so that it receives more heat in passingthrough.

Thecirculation in this boiler takes the usual course, the cold waterpassing in at the lowest point and the hot Water passing out above it aswill be readily understood. The air passes vinto the pipes 29, in thedirection of the arrows V, shown in Fig. 2, and it becomes sufficientlyheated on its way up to combine with the gases of combustion 'as itpasses out through the perfo'rations in the horizontal pipes 30. 35, inFig. 5, represents the `Iire grate.

I claimas my invention-'- 1. A hot water heater consisting of fourhollow main sections forming the substantially square body of theboiler, each section having several series of water tubes connected toone side onlyof the section, each tube of the series communicating withthe water chamber within the section, and having its outer end closed,the tubes in one section passing in between the horizontal rows of tubesin its `opposite section, and the alternate intermediate series ot tubesof the sections forming the other two sides of the boiler, passing intransversely between horizontal rows `of tubes in its opposite section,an ash receptacle upon whichth'e four main sectionsrest, a top coveringthe `main sections having an outlet for the products of combusion, andmeans for securing the sections together, substantially as described. y
